Title: QSO Feedback in Action: Ionization and Dust in the Wind
Abstract:
GMOS/IFU observations of six nearby mergers (Rupke+Veilleux 2012) reveal
massive, wide-angle, kiloparsec-scale outflows, whose velocities are highest
in those systems hosting a QSO. Though the present data provide important
constraints on the properties of these winds, we do not yet know how the QSO
winds connect to the narrow line region (NLR), exactly how dusty the winds
are, or the ionized gas extinctions necessary to exactly measure outflowing
gas masses. We propose to observe five of these six systems with the GMOS IFU
at bluer wavelengths to measure [O III], Hbeta, and Hgamma. We will use these
data to outline the NLR and compute the extinction in the ionized gas. This
will provide important constraints on the physical mechanism behind the QSO
winds, and constrain the dust and ionized content of the outflow. We will
compare our results to data from an extensive multiwavelength campaign of QSO
winds.
